Hello Sonor,
I understand that this is an important addon for you but please read the sticky posts before posting here in the forums:
>"Please read BEFORE asking addon&library questions/post bugs/ask to remove your addon"
I saw that you already posted at the addon comments 2 days ago so just wait a bit longer please for the dev to respond or try to contact him/her via private message on the forum so they will get noticed (as the sticky post all ask for and explain).
Thank you
Edit:
As the addon ships with bundled and outdated libraries and uses LibStub read this pelase and fix most of the issues yourself already:

Remove the subfolder "libs" and change the calls to LibStub("LibAddonMenu-2.0") to LibAddonMenu2 instead as described there.
